Target 4
Halt Species Extinction, Protect Genetic Diversity, and Manage Human-Wildlife Conflicts / Detener la extinción de especies, proteger la diversidad genética y gestionar los conflictos entre el hombre y la fauna salvaje
Adoptar con urgencia medidas de gestión para la recuperación y conservación de las especies, en particular, especies amenazadas, y mantener y restaurar la diversidad genética entre las poblaciones y dentro de ellas, de las especies autóctonas, silvestres y domesticadas, a fin de preservar su potencial adaptativo, entre otras cosas, mediante la conservación in situ y las prácticas de conservación y gestión sostenible, y la gestión eficaz de las interacciones entre seres humanos y fauna y flora silvestres, con miras a reducir al mínimo el conflicto entre los seres humanos y la vida silvestre de cara a la coexistencia.

El contexto
PAME
Unas acciones específicas son esenciales para prevenir las extinciones, revertir las disminuciones y facilitar la recuperación de muchas especies, además de revertir las amenazas y los impulsores de la disminución. Sin tales acciones, el riesgo de extinción para más de un tercio de las especies amenazadas no se reduciría lo suficiente, incluso si todas las demás metas del MMB se implementaran por completo. Las acciones específicas en favor de las especies incluyen la gestión de los hábitats, la reintroducción y el refuerzo de poblaciones, las translocaciones para ampliar las áreas de distribución, la reproducción o propagación en cautividad, la alimentación complementaria, la provisión de sitios de reproducción y otros. Conservar la diversidad genética de las especies silvestres también es importante para su persistencia a largo plazo. Los conflictos entre humanos y vida silvestre están aumentando y amenazan no sólo a las especies, sino también al desarrollo sostenible, la seguridad alimentaria y la vida y el bienestar de los humanos, con impactos que, con mayor frecuencia, afectan más a los más vulnerables y marginados de la sociedad. Se necesitan respuestas integradas a gran escala para minimizar y gestionar los conflictos entre humanos y vida silvestre, promoviendo la coexistencia entre la vida silvestre y las personas.
GSAP SKILLS
The GSAP identifies 7 headline actions in support of Target 4: Assessing and monitoring the status of species, recovery planning, preventing extinction and promoting recovery, ex situ conservation, maintaining genetic diversity, reducing and managing human-wildlife conflict, and learning from conservation success.
An essential task at national level is to identify, and assess the status of, priority species (endemic and near-endemic, threatened, those of socio-economic importance). Countries may consider establishing a IUCN SSC National Species Specialist Group or a National Species Committee / Working Group composed of experts representing all the major taxonomic groups. A few countries have gone one stage further and developed a National Species Strategy to guide species conservation at national level.
Actions
4.1. Assess the conservation status of all species and identify those needing targeted recovery actions.
4.1. Assess the conservation status of all species and identify those needing targeted recovery actions.
Knowledge of the distribution, abundance, trends, and threats provides an essential baseline for conservation planning and action. The primary tools for assessing the status of species are the IUCN Red List of Threatened Species, the Green Status of Species, and the Living Planet Index. Species monitoring is supported by several technical tools.
4.2. Develop and implement a recovery plan (single species, multi-species, site-based, or threat-based) for all species that require one.
4.2. Develop and implement a recovery plan (single species, multi-species, site-based, or threat-based) for all species that require one.
Recovery plans provide the overall framework for species conservation, coordinate action by all stakeholders, reduce duplication, and aid fundraising. Plans may be developed for a single species, several species, a whole taxonomic group, a landscape, ecosystem, or in response to a specific threat and designed for use at global, regional, national, or local level. Key principles of species planning are that it should be inclusive, participatory, and based on sound science. Plans commonly include a long-term Vision, and a Goal, Objectives, and Actions arranged in a hierarchical structure, presented in a logframe format, including timescales, indicators, and the lead responsibilities for implementation.
Many species plans have already been developed which can be used a basis for development of a National Action Plan, a national work plan, or to inform National Biodiversity Strategy and Action Plans. Examples of global-level plans include the Global Strategy for Plant Conservation, which has been adopted by the CBD, and the Amphibian Action Plan.
Guidance on develop new species recovery plans, training courses, and advice are available from SSC and other sources.
4.3. Enact measures to prevent extinctions and recover threatened species.
4.3. Enact measures to prevent extinctions and recover threatened species.
In addition to reversing all the threats and drivers of decline, at least 33% of species are estimated to require specific, targeted actions to prevent their extinction, reverse declines, or enable recovery. Species-specific actions include reintroduction and reinforcement, translocation to expand range, captive breeding or propagation, habitat management, supplementary feeding, provision of breeding sites, and others. There are many examples of species that have been saved from extinction or have had their status improved through effective conservation action. These successful efforts need to be replicated and scaled up to all species that need them.
4.4. Maintain or establish coordinated ex-situ breeding or propagation programmes for all species that require them.
4.4. Maintain or establish coordinated ex-situ breeding or propagation programmes for all species that require them.
Zoos, aquaria, botanic gardens, and seed banks contribute significantly to species conservation by holding “insurance” populations, preserving genetic material, providing stock for reintroductions and reinforcement operations and through their educational and fundraising roles.
4.5. Minimise loss of genetic diversity across all threatened species and retain at least 95% gene diversity in species where it is already depleted.

Assessing and monitoring the genetic diversity of wild species has been relatively neglected until recently. Major advances in genetic and now genomic research have significantly increased the power of molecular analyses and reduced the costs. DNA analysis relies on well-equipped laboratories and trained scientific staff. Therefore, several monitoring and reporting approaches have been developed that use proxy measures where DNA data are not available. Such proxies may include effective population size, range contraction, fragmentation, and others. The headline CBD Indicator for the genetic component of Target 4 is “the proportion of the populations of a species that have an effective population size >500”. A recent study compared five proposed methods for monitoring genetic diversity, and recommended a scorecard system as a unified reporting mechanism by (O’Brien et al. 2022).
4.6. Reduce and manage human-wildlife conflict and its drivers through a holistic, cross-sectoral approach.
4.6. Reduce and manage human-wildlife conflict and its drivers through a holistic, cross-sectoral approach.
As human populations and their need for living space and resources continue to grow, interactions between people and wildlife become more widespread, potentially leading to increased human-wildlife conflict. such as damage to crops, livestock, property, health, and even loss of life. Retaliatory killing of the species involved can lead to decline and local extinction. Furthermore, the impacts of HWC on food security and livelihoods fall mainly on disadvantaged and marginalised rural communities. Resolving these conflicts involves both conservation and sustainable development experts.
4.7. Determine factors governing species conservation success.
4.7. Determine factors governing species conservation success.
Highlighting successful conservation outcomes is essential in order to show that species, habitats, and ecosystems can be restored; to identify the key factors behind success and apply them elsewhere, and to demonstrate decision-makers, donors, and the public that “conservation works”.
